Watergirl and Fireboy are on an adventure again, this time they're in the Crystal Temple. They need each other's help to reach the exit. They both have their advantages and handicaps when they come across obstacles. Watergirl has to avoid the seas of fire, and Fireboy can't walk through water. Help both friends complete all the levels, and collect as many diamonds as possible! There are also teleportation mirrors in the game: Fireboy and Watergirl can walk through them. When they enter at the white side of the mirror, they'll come out somewhere else, still at the white side. It's the same for the black side of the mirror.
